SPECIFICATION forming part of Letters Patent No. 663,499, dated December11, 1900- Application tiled April 23, 1900.

T0 n/ZZ 'Ll/71,0771, it' 'may concern:

Be it known that I, MARTIN JOHNSON, acitizen of the United States, and aresident of Milwaukee, in the county of Milwaukee and State ofVisconsimhave invented certain new and useful Improvements in Car-Moving Mechanism; and I do hereby declare that the following is a full,clear, and exact description thereof.

My invention has for its object to provide for easy moving ofrailway-cars by manual power when a locomotive is not available; and itconsists in certain peculiarities of construction and combination ofparts hereinafter particularly set forth with reference to theaccompanying drawings and subsequently claimed.

Figure l of the drawings represents a partly-sectional view on the planeindicated by line I I in the succeeding figure and illustrates anassemblage of parts in accordance with my invention whereby manual powermay be utilized for easy movement of a railway-car, whether loaded orotherwise; Fig. 2, a detail side elevation, partly broken away and insection, the break being indicated by lines 2 2 in the preceding figure;Fig. 3, a detail transverse section indicated byline 3 3 in the firstlgure; and Fig. 1I, a detail elevation of a ratchet-crank mechanismconstituting part of said invention, parts of this mechanism beingbroken.

Referring by letter to the dra-Wings, A indicates a portion of an axleconstituting part of a railway-car truck, B a wheel on the axle, and Can axle-box ofthe truck. The wheel is cast or otherwise provided with acircular series of outer cogs projecting inward from its rim toconstitute an internal gear D for the engagement of a pinion E, fast ona spindle F, that has its bearings in a block G, seated in asocket-casting H, held on the axlebox C of the truck by the bolts andnuts employed to unite said axle-box and a truss of the truck. Thesocket portion of the casting I-I is shown provided with transversestay-pin b, engaging a notch in block G, and a transverse slip-pin I,engaging said casting and block, serves to hold the latterin detachableconnection with the former. A flexible A colberil NO- 13,919. (Nomodel.)

lar d on the spindle F between its bearings rotates in a notch providedin block G, and thus said spindle is held against longitudinal movement.The outer end of the spindle is made polygonal to fit correspondingapertures formed in the hub e of a ratchet-wheel K and in a crank L, aforked end of the crank heing loose on said hub. In pivotal connectionwith a clipfon the crank is a pawl M, engaged with the ratchet-wheel,this pawl being provided with arms g, that oppose sides of the crank toprevent pivotal displacement of the clip.

In practice it is intended that mechanism consisting of thepinion-carrying spindle F, its bearing-block G, and the slip-pin I, witha crank L and pawl M, shall be kept about railway-car yards and otherplaces having railway-track facilities for connection with car-trucksprovided with socket-castings and wheels having internal gear similar towhat has been specifically set forth in the foregoing. By utilizing thesaid mechanism in conjunction with said truck-Wheel a car or cars may bereadily started and kept moving under control by the exertion of manualpower. When the load is heavy, the hub of the ratchet-wheel K will beslipped on spindle F and the crank L reciprocated in conjunction withpawl M to facilitate rotation of the same; but for empty cars orlight-load cars said crank may be fitted direct to said spindle androtated to accomplish the desired result.

In practice the general construction and arrangement of parts hereinshown and described may be somewhat varied without departure from myinvention.

Having thus described my invention, what I claim as new, and desire to'secure by Letters Patent, is-

l. A railway-car truck having a wheel thereof provided with a circularseries of inwardly-projecting outer cogs, a support on the axle-boxadjacent to said wheel, a bearing-block having detachable connectionwith the support, a crank-spindle rotative in the block, and a pinionfast on the spindle to mesh with the internal gear of the aforesaidwheel.

2. A railwaycar truck having a Wheel thereof provided with a circularseries of inwardly-projecting outer cogs, a support on the axle-boxadjacentto said wheel, a bearing-block having detachable connection withthe support, a Aspindle rotative in the block, a pinion fast ou thespindle to mesh with the internal gear of the aforesaid wheel, and acrank in detachable connection with said spindle.

3. A railway car truck having a wheel thereof provided with a circularseries of inwardly-projecting outer cogs, a support on the axle-boxadjacent to said wheel, a bearing-block having detachableconnectionrwith the support, a spindle rotative i`n' the block; a pinionfast on the spindle tolmeshwiththe internal gear of the aforesaid wheel,a ratchetwheel on the outer end of said spindle, a` crankin` pivotalconnectionwiththe ratchetwheel hub,and a pawl in connection with thecrank toengage said ratchet-wheel.

4. A railwaycar truck having a wheel thereof'providediwith a` circularseries of inwardly-projecting. outer cogs,`a support oni the axle-boxadjacent to said wheel,` a bearing-block having detachable connectionwith the support,\ a spindlerotative in the block,

a pinion fast on thespindle to meslrwith the internal gear of theaforesaid wheel, a ratchetwheel in angular slip it on the outer end ofsaid spindle, aF crank in pivotal connection with the ratchet-Wheel hub,and a pawl in connection with the crank to engage said ratchet-Wheel.

5. A railway-car truck having a wheel thereof provided with a circularseries of inwardly-projectingmcogs; alsupport on the axleboX adjacent tosaid wheel, a bearing-block having detachable connection with thesupport, a spindle rotative in the block, a pinion fast on the spindleto mesh with the internal `gear of the aforesaid wheel,a ratchet-wheel'havin'ga'n an'gularborefor" slip-fit connection In testimony that Iclaimithe/ foregoing L have hereunto set my hand,atMilwaukeegrin thecounty of Milwaukee andv State of Wisconsin, inthe presenceof twowitnesses.
